Thank yo, AO. The position of the sensor is limited by the length of the sensor lead. Not sure how much slack I have and would prefer a piece that somehow allows room for the sensor. Additionally, since I'm not sure how I'll like the bypass and may put the cat back on, I like to plan for other contingencies.

Assuming identical mounting points to the Autometrics model, I have two - make that three - concerns (the same concerns I had with the Autometrics piece).
1. The two rear bolts could potentially be over-stressed. If the area above the jacking point is not TIGHT up against the engine case when the thing is installed, a rotation will be introduced by the jack, with this piece acting as a lever, causing the two rear bolts to be pulled rearward. Yes, I see there is a bolt above the jack point, but you can't expect surface friction of one bolt head and one nut to support the entire weight of the rear of the car, to prevent rotation of the piece.
For reference, this photo is from p-car.com (http://p-car.com/diy/jacktowpoint).
1a. I hope you will be supplying a longer bolt. Photo from above link.
2. The jacking point sits under a different place from where you would normall put the jack without this piece. The case may indeed be equally strong or stronger at this point, I just don't know - it's just a different spot.
3. I'm sure this peice doesn't weigh much, but you are adding some weight to the rear of the car. Parts that don't exist weigh nothing and never break.
